The Brazil international trained at Melwood on Wednesday for the first time since his £29m move to the Merseyside outfit from Bundesliga side Hoffenheim earlier this month.
Firmino could well be another Suarez; he could also be another Alberto Aquilani
Firmino has arrived in the Premier League with a big reputation from the German top-flight after the 23-year-old scored seven times in 33 Bundesliga appearances last term.
But Carragher, who played with former Roma midfielder Aquilani during his spell at Anfield, spoke of the perils of judging a player by his YouTube highlights following the fanfare surrounding Firmino.
“Though 95 per cent of Liverpool supporters have never seen Firmino in action — YouTube doesn’t count — they believe he is already on his way to becoming an icon,” Carrgher wrote in his Daily Mail column.
“He comes from Brazil, his style is similar to Luis Suarez’s and his form for Hoffenheim was brilliant, leaving fans saying: ‘Imagine what he’ll be like for us!’
“That is the mystique of buying players from abroad. Firmino could well be another Suarez; he could also be another Alberto Aquilani.”
The South American has become Liverpool’s third most-expensive signing in their history behind fellow new recruit Christian Benteke and Andy Carroll.
Firmino scored an impressive 38 goals in 140 league appearances for Hoffenheim during the playmaker’s five-year spell at the club.
